The black rhinos have become endangered in large part by the acts of mankind. Rhinos are often hunted for sport or to be sold illegally. Sadly, these rhinos are hunted for their horn, which is later sold. Poaching has played a large role in the drastic decrease in the endangered black rhino population.
Another reason the black rhino has become endangered is because of the loss of their natural habitat. As mankind continues to grow, so does man's need for land. This causes the rhinos to lose their natural habitat and food supplies.
Endangered black rhinos are not only hunted for their horns, but other body parts as well. Body parts, including urine and blood, are often used in remedies, natural medicines, and other rituals in other communities and cultures.
